Original application filed September 18, 1907, Serial No. 393,525. Divided and this application filed December 23, 1907. Serial No. 07,872.

To all whom it may concern:

Be it known that we, MICHAEL F. WEIDEN- BACH and FRANK B. PETERS, citizens of the United States, residing at Minneapolis, in the county of Hennepin and State of Minnesota, have invented certain new and useful Improvements in Combined Heating and Von 393,525, filed September 18, 1907, entitled combined heating and ventilating systems.

The invention consists of the novel devices and combinations of devices hereinafter described and defined in the claims,

In the accompanying drawings which illustrate the invention, like characters indicate like parts throughout the several views.

Referring to the drawings, Figure l is view in side elevation with some parts broken away and some parts in vertical section, illustrating the invention applied in connection with an air jacketed stove, such as usually employed in schoolhouses and stores;

and Fig. 2 is a plan view of the parts shown in Fig. V i

The stove or heaterl which may be of any suitable design, is inclosed within a surrounding jacket 2 that is open at its top and bottom and is spaced apart from said stove, so as to leave an annular air chamber between the same and the stove.

The numeral 3 indicates the smoke pipe which, as shown, leads upward from the top of the stove and may be of the usual or any suitable construction and arrangement.

As the novel feature of this invention, an air heating chamber 4 is applied. directly to the outside surface of the stove 1 in such manner that the embraced side portionof the stove constitutes one side of the said air heating chamber. At its top this air heating chamber 4 is open and at its bottom it is closed except for a cold air intake pipe 5 which leads downwardly and laterally therefrom and through one of the walls 6 of the building to the outside of the building. The fresh air from the outside of the building will be drawn into the room through the intake pipe 5 and will be heated in the compartment 4; and, after it is heated and has attained a rapid upward movement, will be commingled with the hot air which is passing upward through the annular space formed between the stove and the surrounding jacket 2. The cold fresh air drawn in through the pipe 5 is thus directly brought into contact withthe exterior of the stove where it will be very quickly heated. It will also be understood that it is important that the fresh air be heated and given its direct upward movement before it is commingled with the other hot' air circulated through the jacket 2 as above described.

The cold air intake and heating device above described while capable of general use is especially adapted for use in connection with a ventilating system such as that disclosed and claimed in our co-pending application above identified, and wherein the cold foul air is drawn out of the room from a point near the floor.

The term stove is herein used in a broad sense to include a furnace or any kind of fuel burning heater.

VJ hat we claim is:

1. The combination with a stove and a surrounding jacket that is open at both top andibottom, of a heating chamber applied directly to one side of said stove with the embraced portion of the stove constituting one side of said heating chamber, the said chamber having an open top, and a fresh air intake pipe 0 ening into the bottom of said heating cham er, whereby the cold fresh air will first be heated by direct radiationfrom the stove and will then be commingled with the upwardly moving hot air in the space between said stove and surrounding jacket, substantially as described.

ZQThe combination with a stove and a surrounding jacket that is open at both top and bottom, of a heating chamber directly applied to one side of said stove with theem braced portion of the stove constituting one side of said heating chamber and with the l ing hot air in the space between. said stove opposite side of said heating chamber spaced and surrounding jacket. apart from said jacket so as to leave an un In testimony whereof we allix our signaplbstruetecfi airbspacilbetwgenlthe gacket and tures in presence 01' two witnesses.
